The Lowdown
Alright, let’s put this in feet and degrees. Rusty here, converting the numbers so they feel right. We’re looking at 16 days for Costeño Beach. Water temp is about 82°, dead average for this time of year. The story is the same: almost all this run has cross-onshore wind killing the shape. Swell’s coming from the NE, which is the perfect direction for this spot, but the wind just won’t quit. Wave energy is moderate for most of it.
The first real highlight is Tuesday, August 11th in the afternoon. The wind goes glassy, just a light NNE breeze. Swell is a solid 8ft from the NE, but the period is only 7 seconds, so the waves will be a bit soft and fat. Still, glassy conditions here are rare, and the energy jumps to its highest point. There will be some fun, walled-up waves if you pick the right bank.
After that, it’s back to onshore junk until Monday, August 17th in the afternoon. Another window of glass, this time with a light east breeze. Swell is smaller, around 6ft from the NE, period 7 seconds, and the energy is low. It’s clean and tiny, but for a beginner spot that’s consistent, it’s rideable.
Everything else is cross-onshore chop. Saturday the 15th morning shows the biggest swell at 8ft, but the 20 km/h east wind will make it a washing machine. That one’s got over 1000 energy units, meaning plenty of power, but it’s a kite surf day, not a paddle one.
After the 17th, it’s a long, flat, choppy run to the end. Your best bet is the 11th afternoon for the cleanest conditions, even if the waves are a bit short-period. The 17th is a backup for a clean, small session.
Rusty out.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
